saw u or 4 INVENTORS KIKUO HEORI HIROSHI YAMADA HIROSHI ITOH ATTORNEYSTRAVERSE DEVICE IN PACKAGE WINDING APPARATUS The present inventionrelates to a traverse device for a package winding apparatus and moreparticularly to a traverse device for a package winding apparatuswhereby the mode of yarn traversing motions in a traversing mechanism ofa package winding apparatus is controlled by the relative motion,interlocked with said traversing mechanism, of a pattern member and aphotoelectric system, and the mode of yarn traversing motion andconsequently the build-up of a package is accurately controlled to adesired shape.

It is well known that in winding yarn with a textile machine, wherebyyarn or fibers are wound, such as spinning machines, fly frames,twisters, and drawing machines, various types of wound-up packages areproduced by altering the traverse position and traverse length in thetraverse device in the course of the package winding. As one of thetraverse devices to control traverse mode is known a device whereby apair of controlling plates connected to a piston which gives a traversebar up-and-down motion and a pair of controlling plates which altertheir positions according to the progress of traversing motion betweenthe pair of controlling plates, engage with each other to alter thetraverse position-and/or traverse length.

However, in such a traverse device the mode of traverse is mechanicallycontrolled, and so there is naturally a limitation to possible traversemodes and it has a drawback that the structure is generally involved andcomplicated.

Further it is desirable that to alter the shape of the wound packageaccording to the type, size, amount of wound yarn, the mode of traversein the traverse device be altered. In these well-known traverse devices,such operations for alteration are very troublesome and many parts mustbe replaced to alter the traverse mode.

Further it is very often desired in package winding that on the samebobbin or a plurality of bobbins or spools on the same spindle,different typesof traversing operations spaced from each other be.carried out to form a plurality of winding parts or sections spacedfrom each other.

For instance, it is essential that in processing and winding yarn withdraw-twisters, ring twisters, etc., initially wound yarns, which areinconsistent in the number of twist and other properties at the time ofstring-up or the beginning of package winding, be removed from thewinding section for normal yarn and wound separately.

For this reason, these preliminary windings have been wound on a wastespool or a preliminary winding section of a bobbin via travellers set tothe traverse ring positioned lower than the normal yarn winding section,and after the yarn becomes normal and uniform, the traverse ring ispushed up manually or automatically to the normal yarn winding sectionof the bobbin to allow normal package winding.

However, in the prior art it is difficult to carry out traversingmotions of the preliminary windings and to prevent sloughing at thewinding section for the preliminary windings. I t

It is the object of this invention to provide a traverse device for apackage winding apparatus whereby the mode of traverse is controlled bythe relative movement of a pattern member and a photoelectric systeminterlocking with said traversing mechanism such that the traverse mode,that is, the shape of the wound package is easily and optionally formed.

It is another object of the present invention to provide a traversedevice whereby the mode of traverse is easily altered only by a changein pattern plates.

It is further another object of the present invention to provide atraverse device whereby it is possible to carry out a plurality oftraversing operations and to form a plurality of sloughless windingsections spaced from each other.

It is a further object of the present invention to provide a packagewinding apparatus which accelerates the number of revolutions of aspindle at the beginning of winding and decelerates it at the end ofwinding relative to the mode of traverse.

The present invention relates to a traverse device for a package windingapparatus comprising a cylinder provided with a piston capable of makingreciprocating motions by fluid pressure, a traversing mechanism actuatedby the reciprocating motions of said piston, a change over valve forchanging the running direction of the fluid fed to the cylinder, aphotoelectric system consisting of a light source and a light-receivingmechanism, a pattern member determining traverse length adapted to crossthe light paths of the photoelectric system, an oscillating mechanism topermit said pattern member or said photo-electric system to makereciprocating motions, interlocking with said piston, and a drivingmechanism to give reciprocating motions to the pattern member attachedto said oscillating mechanism movable in a direction intersecting thepiston reciprocating direction at right angles or to the photoelectricsystem whereby said change-over valve is actuated by a signal caused togenerated at the edge of the pattern member in the photoelectric systemby the relative motion between the pattern member and the photo-electricsystem.

In FIG. 1 pressure fluid supplied from conduit (1) is passed througheither conduit 3 or 4 by actuating an electro-magnetic valve 2 and isselectively fed into both sides of piston 6 of cylinder 5. When solenoidA of electromegnetic valve 2 is excited, pressure fluid supplied fromconduit 1 is fed into the left-hand side of cylinder 5 via conduit 4 tomove piston 6 in the right direction, whereas when solenoid B ofelectromagnetic valve 2 is excited, pressure fluid supplied from conduit1 is fed into the right-hand side of cylinder 5 via conduit 3 to movepiston 6 in the left-hand direction. The fluid in cylinder 5 present inpiston reciprocating direction is discharged into storage tank 1 viapipe 3 or 4 and electromagnetic valve 2.

To said piston 6 is connected piston rod 8 andto piston rod 8 isconnected traverse bar 7 through a joint. The reciprocating motions ofpiston 6 are transmitted to the traverse bar 7. The traverse bar 7 givespulley 8' reciprocating rotary motion to impart up-and-down motion to aring rail 7' hung by belt 8" from pulley 8" disposed concentrically withpulley 8'. To the ring rail 7 are attached rings. The yarn is wound onbobbin 33 via traveller 42 mounted on the ring while making traversingmotions according to that of the ring rail 7 that is, that of the pistonrod.

The combination of cylinder 5 provided with piston 6 capable of makingreciprocating motions by fluid pressure, traverse bar 7 actuated byreciprocating motion of piston 6, and a change-over for reversing thedirection of the fluid fed into the cylinder 5 is well known in a yarntraverse device.

In the present invention, a photoelectric system comprising a lightsource and light-receiving mechanism and a pattern member fordetermining traverse position and traverse length are arranged in arelative position such that light paths in the photoelectric system areintercepted by the pattern member and that either the pattern member orthe photoelectric system makes reciprocating motions while interlockingwith the piston and linear motion at right angles to the piston runningdirection. For this purpose, to an oscillating mechanism makingreciprocating motion while interlocking with the piston is mounted apattern member or a photoelectric system in a direction intersecting atright angles the piston running direction and a driving mechanism forgiving reciprocating motion to the pattern member or the photoelectricsystem.

The pattern member consists preferably of a pattern holder and a patternplate or plates attached thereto. By replacing a pattern plate, one caneasily change the mode of traverse.

In FIG. 1 the oscillating mechanism and driving mechanism consist of twoshafts l2 and 13 attached to frame 11 of the machine, bracket forholding the pattern member being slidably attached to shafts l2 and 13,worm 22 slidably mounted to shaft 13 and rotatably attached to itaccording to its rotation, screwed shaft 16 rotatably attached topattern member bracket 10, worm wheel 21 meshing with worm 22, attachedto the tip of the screwed shaft 16, and pattern member 17 and 18 meshingwith shaft 16 and movable up and down according to the revolutionsthereof.

In FIG. 1, to rod 9 connected with piston rod 8 is fixed pattern memberbracket 10. This bracket is slidably movable to the left and rightthrough slide bearings 14 and 15 over shafts 12 and 13 fixed to frame 11of the machine. To bracket 10 is attached screwed shaft 16 at rightangles thereto. Pattern holder 17 having a screw meshing with screwedshaft 16 is adapted to move up-and-down along screwed shaft 16, but doesnot rotate therewith. To the pattern holder 17 is fixed pattern plate 18of any shape. Photoelectric system consisting of light source andlight-receiving mechanism 20 with pattern plate 18 interposedtherebetween is disposed in a direction perpendicular to the face ofpattern plate 18. The light source behind the plate is not shown. Thelight-receiving mechanism may be photoelectric cells, photomultipliers,phototransistors, etc. Screwed shaft 16 has worm wheel 21 attached toits lower tip and is rotated by being worm 22 attached to shaft 13.Shaft 13 is rotated by motor 23 through gears 24 and 25.

Pattern plate 18 serves the purpose of intercepting the light from thelight source entering light-receiving mechanism 20. Suppose piston 6moves from left to right to make pattern plate 18 move from left toright. When the left-handedge of pattern plate 18 reaches a lineconnecting the light source and photoelectric cell 20, light entersphotoelectric cell 20 and solenoid B is excited to move piston 6 andpattern plate 18 from right to left. During this movement, photoelectriccell 20 is intercepted by pattern plate 18 until the righthand edge 29of pattern plate 18 reaches a line connecting the light source andphotoelectric cell 20. The cell receives light again and solenoid A isexcited to permit piston 6 and pattern plate 18 to move from left toright. By the repetition of such motions, traverse bar 7 is caused tomake traversing motions.

On the other hand, pattern holder 17 and pattern plate 18 are caused tomove upwardly perpendicular to the oscillating direction of the bracket,independently of the above-mentioned traversing motions, by screwedshaft 16 rotated by motor 23 through gears 24 and 25, driving shaft 13,worm 22 and worm wheel 21. Therefore, traverse length and position varywith the contours of edges 28 and 29 of pattern plate 18.

When a bobbin is full, driving shaft 13 is reversely rotated at highspeeds by a known reversing mechanism. Screwed shaft 16 is thusreversely rotated and pattern plate 18 and pattern holder 17 arereturned to the traverse starting point.

In the present invention, an electric circuit such that electromagneticvalve 2 is operated by the photoelectric system is obvious to oneskilled in the art.

Pattern plate 18 of any material such as translucent synthetic resinplates, metal plates, paper, etc. can be used.

Further in the above described embodiment, the pattern plate 18 wasmoved, and the photoelectric system was maintained stationary. However,the pattern plate, can be allowed to stand still and the photoelectricsystem may be caused to move as described above with regard to thepattern plate. In short, relative motions may be made between patternplate 18 and photoelectric cell 20.

According to the apparatus of this invention, the mode of traverse inthe traversing mechanism can accurately be controlled by the shapes ofthe edges of the pattern plate and the distances therebetween. Furtherby the selective choice of a pattern plate size and shape, traverse ofany mode is possible and the build-up of a yarn package of any shape isobtainable. Moreover by an extremely simple procedure such asreplacement of a pattern plate and change in speeds of relative motionbetween the pattern plate and the photoelectric cell, one can easilychange the mode of traverse.

Pattern plate 18 mounted to pattern holder 17 may be of the variousshapes as shown in FIGS. 3A to 6A. By use of the pattern plates in FIGS.3A, 4A, and 6A, the modes of traverse in FIGS. 3B, 4B, and 6B andpackages 34 of shapes as shown in FIGS. 3C, 4C, and 6C are obtained.Further by use of pattern plate 18 as shown in FIG. 5A and by means ofdriving shaft 13 being reversely rotated at specified intervals, themode of traverse as shown in FIG. 5B and the build-up of the package inFIG. 5C are obtained. In this case, the reverse rotation of drivingshaft 13 may be effected by disposing two photoelectric systems andpreferably limit switches to determine the locality of the reciprocatingmotions at the top and bottom of the pattern member to actuate areversible rotary mechanism attached to motor 23 by the signals from thephotoelectric systems or limit switches.

In one embodiment of the present invention, the pat tern holder cansupport a plurality of pattern plates spaced from each other.

In FIG. 7, a plurality of pattern plates 18 and 19 are set to patternholder 17 spaced from each other. In this diagram, common numerals forcommon elements with FIG. 1 are used to avoid overlapping.

Main pattern plate 18 for determining the build-up of normal yarn on abobbin and sub-pattern plate 19 for determining the build-up of wasteyarn are mounted to pattern holder 17. Photoelectric cell 20 is disposedwhere light is intercepted by either main pattern plate 18 orsub-pattern plate 19.

Main pattern plate 18 and sub-pattern plate 19 serve the purpose ofintercepting a light from light source (not shown) enteringphotoelectric cell 20.

Now, as shown in FIG. 9, when at the start of winding, initially woundnon-uniform yarn 31 is wound onto an off-standard yarn winding part suchas waste spool 32, piston 6 is moved to the right and ring rail 7 withrings attached thereto is lowered to the position of waste spool 32.Pattern member bracket is thus transferred to the right and light tophotoelectric cell is intercepted by sub-pattern 19. When piston 6 andsub-pattern 19 move from left to right and the left-hand edge of thelatter reaches a line between vthe light source and photoelectric cell20, light enters the photoelectric cell, solenoid B is excited, thepiston moves from right to left, and the sub-pattern plate moves fromright to left. During this movement light is intercepted fromphotoelectric cell 20. When the plate 19 moves to the left andright-hand edge 27 of sub-pattern plate 19 reaches a line between thelight source and photoelectric cell 20, the cell receives light again toexcite solenoid A. In like manner sub-pattern plate 19 moves from leftto right together with piston 6. By the repetition of such motions, ringrail 7 is given traversing motions of small traverse length at theposition of waste spool 32 as shown by A, in FIG. 8.

Thus preliminary windings are built on waste spool 32 in good order andif uniform yarn begins to appear, the excitement of solenoid A isstopped one time by sending an optional signal. As a result, regardlessof photoelectric cell 20 receiving light at the right-hand edge ofsub-pattern plate 19, piston 6 moves left and ring rail 7 also moves tothe part 34 of bobbin 33 to wind regular yam as shown in FIG. 8. And atthe same time pattern member bracket 10 moves left resulting inintercepting of light to photoelectric cell 20 by main pattern plate 18.In like manner as for sub-pattern plate 19, at both edges 28 and 29 ofmain pattern plate 18 photoelectric cell 20 receives light and solenoidsA and B are excited to cause piston 6 to move and a reciprocating motionto be imparted to ring rail 7' thereby causing traversing motion for theregular building of a package. That is, in FIG. 8, traversing motions ofA are changed into those of B When they move from A to 8,, a givenlength of transfer tail is wound on space A between the lower end ofregular yarn winding bobbin 34 and the upper end of waste spool 32 asshown in FIG. 9. I

On the other hand, like sub-pattern plate 19, main pattern plate 18makes up-and-down motions independently of the above traversing motionsdue to screwed shaft 16 being rotated by motor 23 through gears 24 and25, driving shaft 13, worm 22, and worm wheel 21. Therefore, thetraverse length varies according to the shapes of edges 28 and 29 ofmain pattern plate 18.

When the building of yarn is finished and a bobbin is full, theexcitement of solenoid B is given one rest. Thus, when piston 6 movesright because the photoelectric cell receives light at left-hand edge 28of main pattern plate 18, solenoid B is not excited. Accordingly, ringrail 7' goes down to waste spool 32 as shown in FIG. 9. And at the sametime pattern member bracket 10 moves right, and main pattern plate 18and sub-pattern plate 19 descent to permit sub-pattern plate 19 tointercept light from photoelectric cell 20. Thus while by the previouslydescribed procedure a small traverse length is obtained by sub-patternplate 19, the apparatus stops. At thus time, while the yarn is allowedto stand on the apparatus, doffing is carried out by cutting off theyarn extending over waste spool 32 and bobbin 33 and an empty bobbin isreplaced. AFter all the spindles have been filled with empty bobbins,the operation is started and the traversing motions of small traverselength as shown in FIG. 8 A are made until standard yarn has appeared topermit the preliminary windings to be wound onto waste spool 32 in goodorder. Thus a transfer tail is formed while ring rail 7' shifts tostandard yarn winding portion 34 of the bobbin and traversing motionsfor standard yarn B are made. 7'

This process is repeated hereinafter.

According to the apparatus of the present invention, since the initiallywound yarn on the waste spool is in good order by traversing motionswithout sloughing, the start-up of all the spindles for the building ofpackages can smoothly be accomplished and neither staining nor thebreakage of the yarn occurs. Hence continuous operations are affectivelypossible until the waste spool is full and the apparatus greatlycontributes to the enhancement of efficiency and increase in yields.

Further the shifting from the waste yarn winding portion to the standardyarn winding portion is mechanically and simultaneously carried out; andconsequently, the length of a transfer tail and wind pitch becomeconstant, resulting in the production of package easily reproducible inthe subsequent processings.

In FIG. 7, to a pattern holder are attached main pattern plate 18 andsub-pattem plate 19 spaced from each other. Instead, a plurality of mainpattern plates may be set to the pattern holder to build a plurality ofyarn build-ups spaced from each other on the same bobbin.

The present invention provides a device comprising a cylinder providedwith a piston capable of having a reciprocating action by fluidpressure, a traversing mechanism actuated by the reciprocating action ofsaid piston, a changeover valve for changing over the feed direction offluid to the cylinder, a photoelectric system consisting of a lightsource and a light-receiving mechanism, a pattern member for determiningtraverse length in the traversing mechanism, so arranged as to interceptthe light paths of the photoelectric system, an oscillating mechanism topermit said pattern member or said photoelectric system to interlockwith said piston, a driving mechanism to allow the pattern member or thephotoelectric system to move up and down in a direction perpendicular tothe piston running direction, a spindle holding a bobbin upon which yarnis wound for rotating the bobbin, a mechanism for driving the spindleand a control mechanism for controlling the number of rotations of thespindle driving mechanism whereby said control mechanism for therotation of the spindle is driven with drive source common with thedriving mechanism of the pattern member or the photoelectric system soas to synchronize with the up-and-down motions of said pattern member orphotoelectric system.

In the device of the present invention, the combination of the spindle,spindle-driving mechanism and traversing mechanism described above inwell-known. The control mechanism for spindle rotation driven by adriving source common with the driving mechanism for the pattern memberor photoelectric system in the traverse device is so disposed as tosynchronize with the mode of traverse formed by the relative motionbetween the pattern member and the photoelectric system and to controlthe number of rotations of the spindle.

In the device of this invention the oscillating mechanism and drivingmechanism for forming the mode of traverse have been mentioned above.The control mechanism for spindle rotation consists preferably of apower transmission gear fitted to a driving shaft having a worm in thedriving mechanism for the pattern member; a reduction gear driventhrough the power transmission mechanism; a cam driven through saidreduction gear and a differential transformer provided with a corehaving a reciprocating action by the rotation of the cam.

In FIG. 10 (Parts common with those in FIG. 1 are expressed in commonnumerals), the construction and function of cylindrical mechanism,traverse mechanism, change-over valve, photoelectric system, patternmember, oscillating mechanism and patternmember-driving mechanism areidentical with those of FIG. 1.

Cam 38 for controlling the speed of spindle rotation is given rotationfrom the left-hand edge of shaft 13 through gear train 36 and reductiongear 37. The displacement of core 40 of differential transformer 39varies with rotation of cam 38. The output of differential transformer39 is thus varied and by use of this signal the speed of rotation ofdriving motor 44 for the spindle is controlled. The control of speed ofrotation of the driving motor 44 by use of the above-mentioneddifferential transformer 39 is well-known.

Pattern plate 18 ascends by the rotation of screwed shaft 16 while ringrail 7' makes traversing motions by the action of electromagnetic valve2, piston 6, oscillating bracket 10, pattern member 18 and photoelectriccell 20. The speed of rotation of screwed shaft 16 is adjustable by thereplacement of the change gear of feed gear train 24 for the patternplate. Thus the traversing motions transmitted to ring rail 7' resemblethe shape of pattern plate 18. Yarn 35 passes through guide 41 and ring42 mounted on the ring rail 7' hanging from traverse bar 7 and is woundon bobbin 33 held on spindle 43 and rotated with spindle driving belt 45while making traversing motions.

In the winding operations if the amount of the upand-down motion ofpattern plate 18 for the time when a bobbin becomes full is renderedconstant and the screw pitch of screwed shaft 16 is constant, the numberof rotations of shaft 16, that is the number of rotations of shaft 13,will be constant and the rotational displacement of cam 38 forcontrolling the number of rotations of the spindle will always beconstant. For instance, suppose when with a rotational displacement ofcam 38 of 300 one bobbin becomes full, a control signal for therotational speed of the spindle is given. If gear train 36 and reductiongear 37 are adjusted so that cam 38 is displaced through 300 by thenumber of rotations of shaft 13 in accordance with the amount ofmovement of the pattern plate, the rotational speed of the spindle canreceive a similar control irrespective of the length of time when thebobbin becomes full. That is, the changes in the rotational speed of aspindle corresponding to a certain displacement of pattern plate 18 areconstant if the shape of cam 38 is constant irrespective of form of theproducts and the drawing and take-up speeds.

Especially in warp winding wherein package diameter and the displacementof the pattern have an almost constant relation with each other, therelation between package diameter and the rotational speed of thespindle are always constant, and even when drawing and take-up speedsare altered, there is no need to alter the rate of variation of spindlerotational speed. This is very convenient for operations.

Hence in the device of the present invention, it is possible to windyarn on a bobbin in an optional shape of package winding and to makeoperations easier by decreasing the number of rotations of the spindlewith an increase in the build-up diameter of the yarn.
